Breakthrough in AI: The Success of DeepSeek’s R1 Model

In a significant advancement in artificial intelligence, the Chinese company DeepSeek has achieved remarkable success with its powerful R1 model. This model caused a stir in the U.S. stock market upon its release in January, and according to documents published alongside the peer-reviewed version in Nature magazine, its success did not rely on training with competitors’ outputs.

Specifications of the R1 Model

The R1 model is designed to excel in “thinking” tasks such as mathematics and programming, positioning itself as a more cost-effective competitor to tools developed by American tech companies. As an “open-weight” model, it is available for anyone to download and has become the most popular in the AI community on the Hugging Face platform, with 10.9 million downloads.

The model is an update of a previous version released in January, detailing how DeepSeek enhanced the standard model to handle thinking tasks. For the first time, supplementary materials revealed the cost of training R1, which amounted to $294,000, in addition to approximately $6 million spent on creating the foundational model upon which R1 is built.

The Peer Review Process

R1 is the first large language model to undergo a peer review process, which many consider a welcome precedent. This level of transparency can help assess the risks these systems may pose. In response to reviewers’ comments, DeepSeek reduced human diagnosis in its descriptions and added clarifications on technical details, including the types of data the model was trained on and its safety.

Innovative Training Techniques

One of DeepSeek’s main innovations is the use of a pure reinforcement learning approach to create R1. The model was rewarded for reaching correct answers, rather than being taught to follow human examples. To enhance efficiency, the model evaluated its attempts using estimates instead of a separate algorithm, a technique known as proximal policy optimization.

This approach has inspired many AI researchers, and it is believed that most research conducted in 2025 related to reinforcement learning in large language models was inspired by R1.

Conclusion

In conclusion, the R1 model remains a strong competitor in the research arena. Although it was not the first in accuracy for scientific tasks like data analysis and visualization, it is considered one of the best models in terms of balance between performance and cost. Researchers are now aiming to apply the methods used in creating R1 to enhance the logical thinking capabilities of current models and expand them into areas beyond mathematics and programming, highlighting that R1 has sparked a true revolution in this field.
